Boston Woman Tackling Peaks At A Record Pace

REVERE, MA - MARCH 13: Vanessa O'Brien trains on Revere Beach by dragging a truck tire up and down the beach, to prepare for a trek to the North Pole. O'Brien is a Bostonian who is a world class mountain climber. She has climbed the 7 Summits (tallest mountain on each continent), and if she makes it to the North Pole when she goes there to hike it next month, then she will have set a new world record for the fastest time to complete the 'Explorers Grand Slam,' meaning climbing the seven summits, and hiking to the North and South Poles in a limited amount of time.
